Description

Technical Field

[0001] The present invention relates to the technical field related to cable laying, and particularly relates to an underground cable bundling device. Background Art

[0002] Cables are a general term for items such as optical cables and electric cables; cables have many uses, mainly for controlling installation, connecting devices, transmitting electricity and other multiple functions, and are an indispensable thing in power, communication and signal transmission. According to the use occasions, they can be divided into several laying methods such as overhead, underground (pipe and direct burial), underwater, wall and tunnel.

[0003] Underground cables refer to cables that are usually buried underground compared with common overhead lines, so they are also called underground cables. Usually, the cable ends are directly inserted into the internal of the underground pipeline and transported forward, resulting in the phenomenon that the cables are prone to cross and overlap during the laying process, thus causing interference problems between the cables; moreover, at present, the bundling method of power cables is relatively simple. Nylon cable ties are mostly used for small-scale cables, and rigid bundling devices with fixed sizes are mostly used for large-scale cables. No matter which method of the existing bundling devices is used, a certain force needs to be applied to bind the cables, resulting in too tight binding of the cables during operation, affecting the heat dissipation and safe operation of the cables.

[0035] As Figures 1-9 shown, the underground cable bundling device of the present invention includes a bottom groove 1 buried underground and used for placing cables. A cover plate 2 for protecting the cables is slidably arranged on the bottom groove 1. One or more first cable slot blocks 3 are arranged in the bottom groove 1. Second cable slot blocks 4 adapted to the first cable slot blocks 3 are arranged in the cover plate 2. The first cable slot blocks 3 and the second cable slot blocks 4 are combined to form a cavity inside, and one or more bundling rings are arranged in the cavity along the width direction of the bottom groove 1;

[0036] A limiting component 5, provided in a plurality and evenly distributed on the inner wall of the bundling ring, is used for multi-point elastic clamping of the cables placed in each bundling ring;

[0037] A partition plate 6 is arranged on the second cable slot block 4 and is used for partitioning the placement space in the bottom groove 1.

[0038] In specific implementation, the bottom groove 1 is buried in a pre-opened cable channel underground, and then the cables to be laid are axially placed corresponding in the open bundling rings of the first cable slot blocks 3. Subsequently, the corresponding number of cables are placed one by one in adjacent bundling rings, and as Figure 8 the corresponding end of one end of the cover plate 2 protruding from the bottom groove 1 is placed, and then horizontally slid and combined, so that the second cable slot blocks 4 installed in the cover plate 2 and the bundling rings with openings on the first cable slot blocks 3 are combined to form a complete bundling ring. The limiting component 5 is operated to perform multi-point limiting clamping on the cables placed in the bundling ring, so as to ensure that after bundling, sufficient space is reserved for the cables to adapt to the thermal expansion and contraction of the cables, and to avoid being too tightly bound at high temperatures, affecting the heat dissipation and safe operation of the cables;

[0039] The partition plate 6, which is also on the inner top surface of the cover plate 2 and welded to the wire groove block two 4, can separate the cables limited within the wire bundling ring during the closing process of the bottom groove 1 and the cover plate 2, avoiding the crossing and overlapping of the cables, so as to prevent interference between different cables.

[0040] It should be noted that the number of the limiting components 5 installed on the inner wall of the wire bundling ring is at least three, which can perform three-point limiting clamping on the cables.

[0041] In an embodiment, the limiting component 5 includes a roller frame 51 arranged on the inner wall of the wire bundling ring, a rack guide rod 52 arranged on the roller frame 51 and extending through to the outside of the wire bundling ring. The inner end of the rack guide rod 52 is fixed with a support plate 53. Two slide rods 54 are slidably penetrated through the support plate 53. A moving frame 55 sliding on the opposite end faces within the roller frame 51 is fixed on the two slide rods 54. And springs are arranged on the two slide rods 54 between the support plate 53 and the moving frame 55. Rollers 56 for abutting against the cables are rotatably arranged on both side faces of the moving frame 55. With such a design, through a plurality of roller frames 51 welded evenly and in a circular array on the inner wall of the wire bundling ring, and the rack guide rod 52 slidably installed in the grooves machined on the roller frame 51, when the rack guide rod 52 is pressed inward by an external force, it will drive the support plate 53 welded to the inner end of the rack guide rod 52 and the rollers 56 installed on the support plate 53 to approach the center of the cable along the radial line until they are abutted and fixed. Among them, during the process of the roller 56 abutting against the cable, when the cable generates heat due to the passage of current during operation, the cable will expand, which will push the abutting roller 56 and the moving frame 55 rotatably installed at both ends of the roller 56 to slide on the inner wall of the roller frame 51 under the support of the slide rods 54 sleeved with springs, so as to adapt to the thermal expansion and contraction of the cable, and avoid being too tightly bound at high temperature, which affects the heat dissipation and safe operation of the cable.

[0042] In an embodiment, a first transmission component 7 for synchronous rotation is arranged at the outer ends of a plurality of roller frames 51 evenly distributed on the inner wall of the wire bundling ring;

[0043] The first transmission component 7 includes a first gear 71 meshed with the side of the rack guide rod 52, and a second gear 72 coaxially installed with the first gear 71. An internal gear ring 73 is meshed with the outer end of the second gear 72, and an outer support ring 74 is rotatably arranged outside the internal gear ring 73. With this design, through the first gear 71 meshed with the teeth on the rack guide rod 52, the second gear 72 coaxially installed on the first gear 71, and the internal gear ring 73 meshed with the outside of the second gear 72, when an external force pushes one side of the rack guide rod 52, it will drive the first gear 71 meshed with its side to rotate, causing the second gear 72 coaxially installed on the first gear 71 to rotate and drive the internal gear ring 73 meshed with the outside of the second gear 72. Furthermore, the two groups of the first gear 71 and the second gear 72 meshed with the remaining part of the internal gear ring 73 will rotate, realizing the use of multiple limiting components 5 evenly distributed in a circumferential array within the wire bundling ring.

[0044] It should be noted that the outer support ring 74 welded on the second wire groove block 4 is rotatably connected to the internal gear ring 73;

[0045] The first gear 71 and the second gear 72 meshed with the internal gear ring 73 and not installed on the second wire groove block 4 are rotatably installed on the first wire groove block 3.

[0046] In one embodiment, a top plate 8 is arranged on the top of the rack guide rod 52 installed on the second wire groove block 4, and a push rod 81 for vertically pushing down multiple rack guide rods 52 connected to the top plate 8 is rotatably arranged on the top plate 8. With this design, through the top plate 8 welded on the top of the rack guide rods 52 that are vertically movable and grooved on the second wire groove block 4 and are on the same horizontal line, and the push rod 81 rotatably installed in the groove on the top plate 8, when the push rod 81 vertically pushes, the vertical force generated will drive multiple rack guide rods 52 horizontally installed on the top plate 8 to move vertically, enabling multiple limiting components 5 evenly distributed in a circumferential array within the wire bundling ring to move synchronously along the radial line, realizing subsequent multi-point clamping of the cable.

[0047] In one embodiment, a second transmission component 9 for closing and locking the bottom groove 1 and the cover plate 2 is arranged on the push rod 81;

[0048] The second transmission component 9 includes a third gear 91 sleeved on the outer wall of the push rod 81, and a first rack 92 and a second rack 93 symmetrically meshed with the third gear 91 on the left and right respectively;

[0049] The thickness of the third gear 91 is less than that of the first rack 92 and the second rack 93, and the third gear 91 moves up and down within the thickness range included by the first rack 92 and the second gear 93. With such a design, by sleeving a fixed third gear 91 on the push rod 81 and sliding and guiding the installation of the first rack 92 and the second rack 93 on the cable slot block two 4, when the third gear 91 rotates, using the gear-rack transmission structure, it drives the two symmetric and meshing left and right first racks 92 and second racks 93 to move away from each other until the two ends of the first rack 92 and the second rack 93 pass through the contacting end faces on the bottom slot 1 and the cover plate 2, so that the bottom slot 1 and the cover plate 2 are fixedly connected.

[0050] It should be noted that the thickness of the third gear 91 is less than that of the first rack 92 and the second rack 93, which can maintain the meshing drive connection between the third gear 91 and the first rack 92 and the second rack 93 while the third gear 91 moves vertically between the first rack 92 and the second rack 93.

[0051] In an embodiment, through slots 10 adapted to and penetrating through the first rack 92 and the second rack 93 are provided on two opposite end faces of the cover plate 2. With such a design, the through slots 10 machined on the cover plate 2 are used for the two separated ends of the first rack 92 and the second rack 93 to pass through.

[0052] In an embodiment, a notch 11 is provided on the end face of the bottom slot 1 that slidably contacts the cover plate 2;

[0053] The notch 11 is used for the first rack 92 or the second rack 93 to translate through. With such a design, the notch 11 machined on the bottom slot 1 enables the first rack 92 and the second rack 93 to horizontally pass through the bottom slot 1 and the cover plate 2 when the first rack 92 and the second rack 93 move away from each other, ensuring the fixed connection effect of the combination of the bottom slot 1 and the cover plate 2.

[0054] In an embodiment, the top of the push rod 81 passes through the top of the cover plate 2, and a position-limiting member for limiting the position of the push rod 81 is provided on the cover plate 2;

[0055] The limiting member includes a frustum-shaped sleeve and a nut. The frustum-shaped sleeve is fixed on the cover plate 2 and is larger at the bottom and smaller at the top. The top of the push rod 81 is inserted into the frustum-shaped sleeve. The frustum-shaped sleeve is provided with a plurality of slots, has an external thread on the outside, and each slot is opened along the height direction of the frustum-shaped sleeve and penetrates the top of the frustum-shaped sleeve. The outside of the frustum-shaped sleeve has an external thread; the nut is matched with the external thread on the frustum-shaped sleeve. Rotating the nut can cause the frustum-shaped sleeve to generate elastic deformation inward, thereby limiting the push rod 81. With such a design, by welding a limiting member with a threaded section at the corresponding position of the push rod 81 on the top surface of the cover plate 2, and the limiting member is composed of a frustum-shaped sleeve with a hollow structure that is larger at the bottom and smaller at the top and several slots evenly spaced at the edge of the sleeve, after the cable fixing and clamping operation is completed within the wire harness loop, by moving the nut downward and under the rotational fixing effect on the outside of the limiting member, a radial acting force on the push rod 81 is generated, so that the push rod 81 is restricted from displacement in the vertical direction, thereby locking the device and avoiding the separation of the bottom groove 1 and the cover plate 2.

[0056] In one embodiment, the wire harness groove block 1 is provided with an embedding groove 31 that is coaxially distributed with the wire harness loop and is adapted to be embedded with the outer support ring 74. With such a design, by turning and processing the embedding groove 31 as shown in Figure 3 in the wire harness groove block 1 and installing a first gear 71 and a second gear 72 corresponding to the limiting component 5 distributed in the wire harness loop in the wire harness groove block 1 in the embedding groove 31, the linkage relationship of a plurality of limiting components 5 evenly and circumferentially arrayed in the wire harness loop is established, the operation is simple, and the construction efficiency is improved.

[0057] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
